$40.00 $30.00

To be used only on CNC machines and routers with automatic feeding.

Using the highest quality sub-micrograin carbide, these bits have a special proprietary edge processing system featuring a super high polished cutting edge with a unique “mirror finish”, resulting in clean cuts, less chance for chip re-welding, a superior surface finish and a longer tool life. Right hand helix, right hand cut.

Specifically designed for a variety CNC machining applications, excellent for cutting:

  • Aluminum
  • Aluminum alloys
  • Aluminum Composite
  • Materials (ACM)
  • Aluminum Composite Panel (ACP)*
  • ALPOLIC® Copper Composite Material (CCM)
  • Alucobond®
  • Alupanel®
  • Brass
  • Copper
  • Dibond®
  • Durabond**
  • Gold
  • Silver
  • Titanium Composite Material (TCM)

Benefits of Mirror-Finish:

  • Razor sharp cutting edge
  • Effortless chip removal
  • Helps prevent chip re-welding
  • Extends tool life
  • Exceptional cut quality

*Aluminum composite panel (ACP) is a type of ACM flat panel that consists of two thin aluminum sheets bonded to a non-aluminum core. ACPs are frequently used for building facades, external cladding, insulation and signage. **Durabond is a polyethylene core with 0.3mm colored aluminum sheet on either side, pre-finished requiring no decoration.

Warning: Never attempt to cut ferrous metals with these bits.

Inspect cut quality, adjust feed / speed accordingly.

For optimal results and extended tool life use mist lubricant system or air cooling.

Maximum RPM: 35,000

The recommended feed rate for aluminum is 3 meters/min or 120 inch/min at 18,000 RPM.
